NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS ​ ​ 1. Organization and Nature of Business ​ Overview ​ Aclaris Therapeutics, Inc. was incorporated under the laws of the State of Delaware in 2012. Aclaris Therapeutics, Inc. and its wholly owned subsidiaries are referred to collectively as the “Company.” ​ The Company is a clinical-stage biopharmaceutical company focused on developing novel drug candidates for immuno-inflammatory diseases. The Company’s proprietary KINect drug discovery platform combined with its preclinical development capabilities allows the Company to identify and advance potential drug candidates that it may develop independently or in collaboration with third parties. In addition to identifying and developing its novel drug candidates, the Company is pursuing strategic alternatives, including identifying and consummating transactions with third-party partners, to further develop, obtain marketing approval for and/or commercialize its novel drug candidates. The Company also provides contract research services to third parties enabled by its early-stage research and development expertise. ​ Liquidity ​ The Company’s condensed consolidated financial statements have been prepared on the basis of continuity of operations, realization of assets and the satisfaction of liabilities in the ordinary course of business. As of June 30, 2024, the Company had cash, cash equivalents and marketable securities of $ 149.9 million and an accumulated deficit of $ 798.7 million. Since inception, the Company has incurred net losses and negative cash flows from its operations. There can be no assurance that profitable operations will ever be achieved, and, if achieved, will be sustained on a continuing basis. In addition, development activities, including clinical and preclinical testing of the Company’s drug candidates, will require significant additional financing. The future viability of the Company is dependent on its ability to successfully develop its drug candidates and to generate revenue from identifying and consummating transactions with third-party partners to further develop, obtain marketing approval for and/or commercialize its development assets or to raise additional capital to finance its operations. The Company will require additional capital to develop its drug candidates and to support its discovery efforts. ​ Additional funds may not be available on a timely basis, on commercially acceptable terms, or at all, and such funds, if raised, may not be sufficient to enable the Company to continue to implement its long-term business strategy. The Company's ability to raise additional capital may be adversely impacted by potentially worsening global economic conditions caused by a variety of factors including geopolitical tensions, heightened interest rates, and inflationary pressures. If the Company is unable to raise sufficient additional capital or generate revenue from transactions with potential third-party partners for the development and/or commercialization of its drug candidates, it may need to substantially curtail planned operations. The Company’s failure to raise capital as and when needed could have a negative impact on its financial condition and ability to pursue its business strategies. ​ In accordance with Accounting Standards Codification (“ASC”) Subtopic 205-40, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, the Company evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that its condensed consolidated financial statements are issued. As of the report date, the Company does not believe that substantial doubt exists about its ability to continue as a going concern. The Company believes its existing cash, cash equivalents and marketable securities are sufficient to fund its operating and capital expenditure requirements for a period greater than 12 months from the date of issuance of these condensed consolidated financial statements. 6 Table of Contents ​ 2. Summary of Significant Accounting Policies ​ Unaudited Interim Financial Information ​ The accompanying condensed consolidated balance sheet as of June 30, 2024, the condensed consolidated statements of operations and comprehensive loss for the three and six months ended June 30, 2024 and 2023, the condensed consolidated statement of stockholders’ equity for the three and six months ended June 30, 2024 and 2023, and the condensed consolidated statements of cash flows for the six months ended June 30, 2024 and 2023 are unaudited. The unaudited interim condensed consolidated financial statements have been prepared on the same basis as the audited annual financial statements contained in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on February 27, 2024 and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the Company’s financial position as of June 30, 2024, the results of its operations and comprehensive loss for the three and six months ended June 30, 2024 and 2023, its changes in stockholders’ equity for the three and six months ended June 30, 2024 and 2023 and its cash flows for the six months ended June 30, 2024 and 2023. The condensed consolidated balance sheet data as of December 31, 2023 was derived from audited financial statements but does not include all disclosures required by generally accepted accounting principles in the United States (“GAAP”). The financial data and other information disclosed in these notes related to the three and six months ended June 30, 2024 and 2023 are unaudited. The results for the three and six months ended June 30, 2024 are not necessarily indicative of results to be expected for the year ending December 31, 2024, any other interim periods, or any future year or period. The unaudited interim financial statements of the Company included herein have been prepared, pursuant to the rules and regulations of the SEC. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted from this report, as is permitted by such rules and regulations. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto for the year ended December 31, 2023 included in the Company’s Annual Report on Form 10-K filed with the SEC on February 27, 2024. ​ Basis of Presentation ​ The accompanying condensed consolidated financial statements have been prepared in conformity with GAAP. The condensed consolidated financial statements of the Company include the accounts of the operating parent company, Aclaris Therapeutics, Inc., and its wholly owned subsidiaries. All intercompany transactions have been eliminated. Based upon the nature and size of the Company’s revenue, the Company believes that gross profit does not provide a meaningful measure of profitability and, therefore, has not included a line item for gross profit on the condensed consolidated statement of operations. ​ Use of Estimates ​ The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting periods. Significant estimates and assumptions reflected in these financial statements include, but are not limited to, contingent consideration and the valuation of stock-based awards. Estimates are periodically reviewed in light of changes in circumstances, facts and experience. As of the date of issuance of these financial statements, the Company is not aware of any specific event or circumstance that would require an update to its estimates, assumptions and judgments or revise the carrying value of its assets or liabilities. Actual results could differ from the Company’s estimates. ​ Reclassifications ​ Certain prior year amounts have been reclassified to conform to the current year’s financial statement presentation. ​ ​ ​ 7 Table of Contents Significant Accounting Policies ​ The Company’s significant accounting policies are disclosed in the audited consolidated financial statements for the year ended December 31, 2023 included in the Company’s Annual Report on Form 10-K filed with the SEC on February 27, 2024. There have been no changes to the Company’s significant accounting policies from those disclosed in the annual report. ​ Contingent Consideration ​ The Company records a contingent consideration liability related to future potential payments resulting from the acquisition of Confluence Life Sciences, Inc. (now known as Aclaris Life Sciences, Inc.) (“Confluence”) based upon significant unobservable inputs including the achievement of regulatory and commercial milestones, as well as estimated future sales levels and the discount rates applied to calculate the present value of the potential payments. Significant judgement is involved in determining the appropriateness of these assumptions. These assumptions are considered Level 3 inputs. Revaluation of the contingent consideration liability can result from changes to one or more of these assumptions. The Company evaluates the fair value estimate of the contingent consideration liability on a quarterly basis with changes, if any, recorded as income or expense in the condensed consolidated statement of operations. ​ The fair value of contingent consideration is estimated using a probability-weighted expected payment model for regulatory milestone payments and a Monte Carlo simulation model for commercial milestone and royalty payments and then applying a risk-adjusted discount rate to calculate the present value of the potential payments. Significant assumptions used in the Company’s estimates include the probability of achieving regulatory milestones and commencing commercialization, which are based on an asset’s current stage of development and a review of existing clinical data. Probability of success assumptions ranged between 17 % and 40 % at June 30, 2024. Additionally, estimated future sales levels and the risk-adjusted discount rate applied to the potential payments are also significant assumptions used in calculating the fair value. The discount rate ranged between 7.0 % and 8.2 % depending on the year of each potential payment. ​ Revenue Recognition ​ The Company accounts for revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers. Under ASC Topic 606, revenue is recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. ​ To determine revenue recognition in accordance with ASC Topic 606, the Company performs the following five steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract, and (v) recognize revenue when (or as) performance obligations are satisfied. At contract inception, the Company assesses the goods or services promised within a contract with a customer to identify the performance obligations, and to determine if they are distinct. The Company recognizes the revenue that is allocated to each distinct performance obligation when (or as) that performance obligation is satisfied. The Company only recognizes revenue when collection of the consideration it is entitled to under a contract with a customer is probable. ​ Contract Research Revenue ​ The Company earns contract research revenue from the provision of laboratory services. Contract research revenue is generally evidenced by contracts with clients which are on an agreed upon fixed-price, fee-for-service basis and are generally billed on a monthly basis in arrears for services rendered. Revenue related to these contracts is generally recognized as the laboratory services are performed, based upon the rates specified in the contracts. Under ASC Topic 606, the Company elected to apply the “right to invoice” practical expedient when recognizing contract research revenue and as such, recognizes revenue in the amount which it has the right to invoice. ASC Topic 606 also provides an optional exemption, which the Company has elected to apply, from disclosing remaining performance obligations when revenue is recognized from the satisfaction of the performance obligation in accordance with the “right to invoice” practical expedient. 8 Table of Contents ​ Licensing Revenue ​ Licenses of Intellectual Property – The Company recognizes revenue received from non-refundable, upfront fees related to the licensing of intellectual property when the intellectual property is determined to be distinct from the other performance obligations identified in the arrangement, the license has been transferred to the customer, and the customer is able to use and benefit from the license. Milestone and Royalty Payments – The Company considers any future potential milestones and sales-based royalties to be variable consideration. The Company recognizes revenue from development, regulatory and anniversary milestone payments as they are achieved. The Company recognizes revenue from commercial milestones and royalty payments as the sales occur. Discontinued Operations ​ As of June 30, 2024 and December 31, 2023, the Company had $ 2.2 million in discontinued operations reported as other current liabilities in the Company’s consolidated balance sheet, related to discontinued commercial products. ​ Recently Issued Accounting Pronouncements ​ In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” This standard requires disclosure of significant segment expenses and other segment items by reportable segment. This ASU becomes effective for annual periods beginning in 2024 and interim periods in 2025. The Company is assessing the impact of this ASU and upon adoption expects that any impact would be limited to additional segment expense disclosures in the footnotes to the Company’s consolidated financial statements. ​ In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” This standard enhances disclosures related to income taxes, including the rate reconciliation and information on income taxes paid. This ASU becomes effective January 1, 2025. The Company is currently assessing the impact of this ASU. ​ ​ 3.

The Company’s marketable securities as of June 30, 2024 consisted of corporate debt, asset-backed debt, foreign government agency debt, and U.S. government and government agency debt securities, which were all valued based upon Level 2 inputs. The Company’s marketable securities as of December 31, 2023 consisted of commercial paper and corporate debt, asset-backed debt, foreign government agency debt, and U.S. government and government agency debt securities, which were all valued based upon Level 2 inputs. ​ In determining the fair value of its Level 2 investments, the Company relies on quoted prices for identical securities in markets that are not active. These quoted prices are obtained by the Company with the assistance of a third-party pricing service based on available trade, bid and other observable market data for identical securities. During the three and six months ended June 30, 2024 and 2023, there were no transfers into or out of Level 3. ​ The overall $ 3.0 million increase in the fair value of the contingent consideration liability during the six months ended June 30, 2024 was primarily due to changes in estimated sales levels and changes to the probability of success for certain drug candidates. ​ As of June 30, 2024 and December 31, 2023, the fair value of the Company’s available-for-sale marketable securities by type of security was as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2024 ​ ​ ​ ​ ​ Gross ​ Gross ​ ​ ​ ​ ​ Book ​ Unrealized ​ Unrealized ​ Fair (In thousands) ​ Value ​ Gain ​ Loss ​ Value Marketable securities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Corporate debt securities (1) ​ $ 68,307 ​ $ 6 ​ $ ( 210 ) ​ $ 68,103 Asset-backed debt securities (2) ​ ​ 5,023 ​ ​ — ​ ​ ( 22 ) ​ ​ 5,001 Foreign government agency debt securities ​ ​ 4,804 ​ ​ 1 ​ ​ — ​ ​ 4,805 U.S. government and government agency debt securities (3) ​ ​ 49,375 ​ ​ — ​ ​ ( 247 ) ​ ​ 49,128 Total marketable securities ​ $ 127,509 ​ $ 7 ​ $ ( 479 ) ​ $ 127,037 (1) Included in Corporate debt securities is $ 33.7 million with maturity dates between one and two years . ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (2) Included in Asset-backed debt securities is $ 0.1 million with maturity dates between one and two years . ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (3) Included in U.S. government and government agency debt securities is $ 5.0 million with maturity dates between one and two years . ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 10 Table of Contents ​ ​ December 31, 2023 ​ ​ ​ ​ ​ Gross ​ Gross ​ ​ ​ ​ ​ Book ​ Unrealized ​ Unrealized ​ Fair (In thousands) ​ Value ​ Gain ​ Loss ​ Value Marketable securities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Corporate debt securities (1) ​ $ 52,362 ​ $ 65 ​ $ ( 142 ) ​ $ 52,285 Commercial paper ​ ​ 12,345 ​ ​ 2 ​ ​ ( 1 ) ​ ​ 12,346 Asset-backed debt securities (2) ​ ​ 10,953 ​ ​ 42 ​ ​ ( 30 ) ​ ​ 10,965 Foreign government agency debt securities (3) ​ ​ 4,698 ​ ​ 43 ​ ​ — ​ ​ 4,741 U.S. government and government agency debt securities (4) ​ ​ 61,750 ​ ​ 8 ​ ​ ( 96 ) ​ ​ 61,662 Total marketable securities ​ $ 142,108 ​ $ 160 ​ $ ( 269 ) ​ $ 141,999 (1) Included in Corporate debt securities is $ 28.0 million with maturity dates between one and two years . ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (2) Included in Asset-backed debt securities is $ 6.2 million with maturity dates between one and three years . ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (3) Included in Foreign government agency debt securities is $ 4.7 million with a maturity date between one and two years . ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (4) Included in U.S. government and government agency debt securities is $ 23.9 million with maturity dates between one and two years . ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 4.
